However, in addition to the inconvenience of increasing the reversing process, the work is performed at a low position in the space of the connecting member in a state of being laid on the floor surface, so the work is performed in a crouched and cramped posture, which is extremely work. There is a problem of bad sex. In addition, when the cover member is attached to the connecting piece of the connecting member, the opening of the space is closed, so the cover member is removed every time the wiring is inspected or redone, and the desk is turned upside down or below the top plate. You are forced to work by sneaking into the space of.

Motor storage units 11 and 11 are provided, and a pair of the first wiring rods 4 and 4 are connected in parallel between the two main rods 14 and 14 in the vicinity of the front and back in the depth direction of the motor storage unit 11, and both first wiring rods 4 The second wiring rods 5 and 5 are connected to the proximity positions of the motor storage portions 11 and 11 between the two motor rods 11 and 4, respectively, and the intermediate positions of the second wiring rods 5 and 5 between the first wiring rods 4 and 4 respectively. The third wiring rod 6 is connected to the rod, and all the accommodation spaces 7 of the wiring rods 4, 5 and 6 are communicated with each other. The support frame 2 is sufficiently connected because the main rods 14 and 14 on both sides are connected by a ladder-like structure composed of the first wiring rods 4, 4, the second wiring rods 5, and 5, and the third wiring rod 6. Since all the accommodation spaces 7 of each wiring rod are communicated with each other while ensuring the top plate support strength, the degree of freedom of wiring of the cords C is high, and the long surplus portion of the cords C is also a continuous accommodation space. It can be wound and accommodated in the loop portion made in 7. Further, in the case of a type having a wide depth of the top plate 3 or a type having a long lateral length of the top plate 3, in order to increase the supporting strength of the top plate 3, the first wiring rods 4 and Reinforcing rods 15 and 15 are connected between the main rods 14 and 14 at the outer positions of 4.

前記支持フレーム２には、前記電動昇降機構の駆動モータを収容するモータ格納部１１，１１を備えるとともに、適所に前記駆動モータ１０を制御する制御ユニット１２を装着している。前記支持フレーム２は、複数の杆体を組み合わせて構成し、前記収容空間７を有する前記配線杆体も前述のように複数種類から構成されている。しかし、本発明は配線杆体が、第１配線杆体４のみから構成される場合も含み、その場合には、第１配線杆体４が前記モータ格納部１１及び前記制御ユニット１２の近傍に配置され、前記第１配線杆体４の収容空間７に配線したコード類Ｃを、直接に前記駆動モータ１０及び前記制御ユニット１２に接続することができる。また、前述のように前記第１配線杆体４に分岐連結した第２配線杆体５を、前記モータ格納部１１に近接配置する場合には、前記第１配線杆体４と第２配線杆体５の各々の収容空間７，７が連通しているので、これら収容空間７を通してコード類Ｃを前記駆動モータ１０に接続することができる。これらの場合、前記制御ユニット１２は、前記第１配線杆体４と第２配線杆体５の何れかの収納空間７内に配置することも可能である。 The support frame 2 is provided with motor storage units 11 and 11 for accommodating the drive motor of the electric elevating mechanism, and is equipped with a control unit 12 for controlling the drive motor 10 at an appropriate position. The support frame 2 is configured by combining a plurality of rods, and the wiring rod having the accommodation space 7 is also composed of a plurality of types as described above. However, the present invention also includes a case where the wiring rod is composed of only the first wiring rod 4, in which case the first wiring rod 4 is arranged in the vicinity of the motor storage unit 11 and the control unit 12. The cords C wired in the accommodation space 7 of the first wiring rod 4 can be directly connected to the drive motor 10 and the control unit 12. Further, when the second wiring rod 5 branched and connected to the first wiring rod 4 as described above is arranged close to the motor storage portion 11, each of the first wiring rod 4 and the second wiring rod 5 is arranged. Since the accommodation spaces 7 and 7 of the above are communicated with each other, the cords C can be connected to the drive motor 10 through these accommodation spaces 7. In these cases, the control unit 12 can be arranged in the storage space 7 of either the first wiring rod 4 or the second wiring rod 5.

また、本実施形態では、前記第１配線杆体４に各々の収容空間７，７が連通するように第３配線杆体６を分岐連結している。そして、前記第３配線杆体６の収容空間７に前記制御ユニット１２を配設している。それにより、前記第１配線杆体４、第２配線杆体５及び第３配線杆体６の収容空間７を通して、前記駆動モータ１０と前記制御ユニット１２をコード類Ｃで接続できるようになっている。ここで、前記第３配線杆体６は、天板３の中央部に位置し、左右の脚体１，１に対して等距離に設定してあり、共通の制御ユニット１２から左右の駆動モータ１０，１０に同じ態様で配線することができる。こうして、前記支持フレーム２を構成する第３配線杆体６の収容空間７内に制御ユニット１２を露出することなく配設することができ、駆動モータ１０との間を接続するコード類Ｃや電力を供給する電源ケーブルやスイッチに接続するケーブル等のコード類Ｃも全て支持フレーム２内に露出することなく配線することができる。尚、本実施形態では、前記制御ユニット１２を前記第３配線杆体６の収容空間７に配設したが、前記第１配線杆体４の収容空間７内又は該第１配線杆体４に近接して配置した収納ボックス内に格納しても良い。 Further, in the present embodiment, the third wiring rod 6 is branched and connected so that the respective accommodation spaces 7 and 7 communicate with the first wiring rod 4. Then, the control unit 12 is arranged in the accommodation space 7 of the third wiring rod 6. As a result, the drive motor 10 and the control unit 12 can be connected by cords C through the accommodation space 7 of the first wiring rod 4, the second wiring rod 5, and the third wiring rod 6. Here, the third wiring rod 6 is located at the center of the top plate 3 and is set to be equidistant from the left and right leg bodies 1 and 1, and the left and right drive motors 10 are set from the common control unit 12. , 10 can be wired in the same manner. In this way, the control unit 12 can be arranged in the accommodation space 7 of the third wiring rod 6 constituting the support frame 2 without exposing the control unit 12, and the cords C and the electric power connected to the drive motor 10 can be provided. All the cords C such as the power cable to be supplied and the cable connected to the switch can be wired without being exposed in the support frame 2. In the present embodiment, the control unit 12 is arranged in the accommodation space 7 of the third wiring rod 6, but is in the accommodation space 7 of the first wiring rod 4 or close to the first wiring rod 4. It may be stored in the arranged storage box.

図５〜図９において、前記主杆体１４の上面は天板取付面１６となっており、前記支持フレーム２に天板３を載置して取付けた場合には、該天板取付面１６に前記天板３の下面が当接する。前述のように、前記支持フレーム２の配線杆体４，５，６には、上方開放した収容空間７を有しているので、前記天板３を支持フレーム２に取付ける前の状態で、上方からの作業で前記制御ユニット１２を第１配線杆体６の収容空間７内に取付け、各種のコード類Ｃを収容空間７に落とし込んで配線することができる。 In FIGS. 5 to 9, the upper surface of the main rod 14 is a top plate mounting surface 16, and when the top plate 3 is placed and mounted on the support frame 2, it is mounted on the top plate mounting surface 16. The lower surface of the top plate 3 comes into contact with the top plate 3. As described above, since the wiring rods 4, 5 and 6 of the support frame 2 have the accommodation space 7 opened upward, the top plate 3 is in a state before being attached to the support frame 2 from above. The control unit 12 can be installed in the accommodation space 7 of the first wiring rod 6 and various cords C can be dropped into the accommodation space 7 for wiring.

また、本発明では、前記支持フレーム２に天板３を載置して取付けた後に、点検や配線のやり直しができるようになっている。そのため、図６〜図９に示すように、前記第１配線杆体４と第２配線杆体５は、前記支持フレーム２に前記天板３を取付けた状態で該天板３下面との間に前記収容空間７と連通する挿通溝１７を形成するように側面部の高さが設定されている。前記挿通溝１７を通して第１配線杆体４及び第２配線杆体５の収容空間７に対して側方からコード類Ｃを出し入れすることができるようにしている。 Further, in the present invention, after the top plate 3 is placed and attached to the support frame 2, inspection and rewiring can be performed again. Therefore, as shown in FIGS. 6 to 9, the first wiring rod 4 and the second wiring rod 5 are placed between the top plate 3 and the lower surface of the top plate 3 in a state where the top plate 3 is attached to the support frame 2. The height of the side surface portion is set so as to form an insertion groove 17 that communicates with the accommodation space 7. The cords C can be taken in and out from the side of the accommodation space 7 of the first wiring rod 4 and the second wiring rod 5 through the insertion groove 17.

具体的には、前記第１配線杆体４は、図５〜図１１に示すように、上方開放した断面略コ字形のチャンネル状本体部１８の内部がコード類の収容空間７となり、該本体部１８の一側縁に沿って外向きに前記天板３の下面に当接して取付けるための固定板１９を設け、他側縁に沿って内向きに前記固定板１９よりも低い位置に補強板２０を設けた形状である。前記第１配線杆体４は、板金で作製できて、剛性の高い断面構造であるので、支持フレーム２の主要部材となり、天板３を確実に支持することができるとともに、内部の収容空間７をコード類Ｃの配線に利用することができる。また、前記挿通溝１７からコード類Ｃを収容空間７に落とし込んで配線した際にも、収容空間７内に有する補強板２０でコード類Ｃを保持し、コード類Ｃのはみ出し、脱落を防止できる。また、前記第２配線杆体５は、図５、図８〜図１０に示すように、上方開放した断面略コ字形のチャンネル状本体部２１の両側壁の上縁を内向きに折曲板２２，２２を形成した形状であり、該折曲板２２，２２の位置は前記天板取付面１６より低い位置に設定している。つまり、前記第１配線杆体４の補強板２０と天板３下面の間の空間、及び前記第２配線杆体５の両折曲板２２，２２と天板３下面の間の空間が前記挿通溝１７となる。 Specifically, in the first wiring rod 4, as shown in FIGS. 5 to 11, the inside of the channel-shaped main body 18 having a substantially U-shaped cross section opened upward becomes a storage space 7 for cords, and the main body portion A fixing plate 19 for mounting by abutting the lower surface of the top plate 3 outward along one side edge of 18 is provided, and a reinforcing plate is provided inward along the other side edge at a position lower than the fixing plate 19. It is a shape provided with 20. Since the first wiring rod 4 can be made of sheet metal and has a highly rigid cross-sectional structure, it can be a main member of the support frame 2, can reliably support the top plate 3, and can provide an internal accommodation space 7. It can be used for wiring the cords C. Further, even when the cords C are dropped into the accommodation space 7 from the insertion groove 17 and wired, the cords C can be held by the reinforcing plate 20 held in the accommodation space 7 to prevent the cords C from protruding or falling off. .. Further, as shown in FIGS. 5 and 8 to 10, the second wiring rod 5 is a bent plate 22 inward with the upper edges of both side walls of a channel-shaped main body 21 having a substantially U-shaped cross section opened upward. , 22 is formed, and the positions of the bent plates 22 and 22 are set lower than the top plate mounting surface 16. That is, the space between the reinforcing plate 20 of the first wiring rod 4 and the lower surface of the top plate 3 and the space between the bent plates 22 and 22 of the second wiring rod 5 and the lower surface of the top plate 3 are the insertion grooves. It becomes 17.

ここで、図５に示すように、前記第１配線杆体４の固定板１９は外側（天板中心から離れた側）に位置し、補強板２０は内側（天板中心寄り側）に位置し、また前記第２配線杆体５の両折曲板２２，２２は左右両側に位置しているので、前記第１配線杆体４と第２配線杆体５と天板３との間に形成される挿通溝１７は全て連続した空間となっている。それにより、前記コード類Ｃは前記挿通溝１７を通して収容空間７に配線できるのである。つまり、前記支持フレーム２と天板３下面との間に形成される挿通溝１７を利用して、第１配線杆体４と第２配線杆体５の収容空間７に対してコード類Ｃを出し入れすることができ、点検や配線のやり直しを配線杆体の側方から容易に行うことができ、天板３の下方空間に潜り込んでの作業であっても、作業効率が良いので短時間で済ませることができる。 Here, as shown in FIG. 5, the fixing plate 19 of the first wiring rod 4 is located on the outside (the side away from the center of the top plate), and the reinforcing plate 20 is located on the inside (the side closer to the center of the top plate). Further, since the bent plates 22 and 22 of the second wiring rod 5 are located on both the left and right sides, the insertion formed between the first wiring rod 4 and the second wiring rod 5 and the top plate 3 is formed. The grooves 17 are all continuous spaces. As a result, the cords C can be wired to the accommodation space 7 through the insertion groove 17. That is, the cords C are taken in and out of the accommodation space 7 of the first wiring rod 4 and the second wiring rod 5 by using the insertion groove 17 formed between the support frame 2 and the lower surface of the top plate 3. It is possible to easily perform inspections and rewiring from the side of the wiring rod, and even if the work is done by sneaking into the space below the top plate 3, the work efficiency is good, so it can be completed in a short time. it can.

また、前記第３配線杆体６は、図５〜図７及び図１１に示すように、上方開放した断面略コ字形のチャンネル状本体部２３からなり、該本体部２３の底面２４の両端部で、前記制御ユニット１２の両端部に設けたコネクタ接続部に対応する位置に、点検用の開口２５を形成してあり、また両側壁２６，２６の上端高さは前記前記天板取付面１６より低い位置であるが、この場所にはコード類Ｃを配線する必要がなく、また制御ユニット１２の保護のためにも高く設定している。 Further, as shown in FIGS. 5 to 7 and 11, the third wiring rod 6 is composed of a channel-shaped main body 23 having a substantially U-shaped cross section opened upward, and is formed at both ends of the bottom surface 24 of the main body 23. , Inspection openings 25 are formed at positions corresponding to the connector connection portions provided at both ends of the control unit 12, and the heights of the upper ends of the side walls 26, 26 are higher than the top plate mounting surface 16. Although it is a low position, it is not necessary to wire the cords C in this place, and it is set high for the protection of the control unit 12.

ここで、本実施形態では、前記第１配線杆体４に対する前記第２配線杆体５と前記第３配線杆体６の分岐連結部（交差部）において、各配線杆体の切断端面に直接コード類Ｃが触れないように工夫している。図１０及び図１１に示すように、切断端面は他の部材の折曲片２７で覆われ、また角部は丸く面取り加工してＲ部２８を形成している。前記折曲片２７は、直角に折曲して他の部材の切断端面を隠し、あるいはハゼ折り（１８０度折り曲げ）して他の部材の切断端面を抱き込んで隠すとともに、二つの部材の連結の役目も果たしている。 Here, in the present embodiment, at the branch connecting portion (intersection portion) of the second wiring rod 5 and the third wiring rod 6 with respect to the first wiring rod 4, the cords C are directly attached to the cut end faces of the respective wiring rods. I try not to touch it. As shown in FIGS. 10 and 11, the cut end face is covered with a bent piece 27 of another member, and the corner portion is rounded and chamfered to form the R portion 28. The bent piece 27 is bent at a right angle to hide the cut end face of another member, or is folded (bent 180 degrees) to embrace and hide the cut end face of another member, and is connected to the two members. It also plays the role of.
